Spacegun Design

Playing Starfield (shit game btw) had me thinking about how you'd actually design a gun for functionality in space infantry combat.

As far as I understand, most guns now would work fine in space, since the propellant has it's own oxidizer. The main issue will come to weight and overheating.

A lot of guns in starfield are caseless, which makes sense if you're trying to save weight- but it makes no sense if we're considering the lack of radiators. In a vacuum, guns would overheat way faster. Ejecting brass shells is actually a great way of helping remove some of that heat. Of course, if you're fighting in orbit then maybe you don't want the hazard of shell casings flying around in the upper atmosphere. Maybe caseless rounds with some sort of water cooling/radiator on the gun, or with the gun integrated into an existing cooling system on your space suit would make sense?

      Co2 guns are already able to achieve pretty decent velocities. Considering you'd need pressurized gas already to power stuff like thrusters, would it not just make more sense to go down that route?

      Or maybe making guns out of some sort of composite material that doesn't transfer heat well.

      Because airguns are trash. You get maybe 10 shots of merely acceptable performance out of a full tank, and you've vented a lot of gas. If you outfitted your theoretical space soldier with an airgun, and then outfitted a second soldier with a traditional rifle with the same number of shots, the second would be lighter, have a more capable and reliable weapon, and would not experience any significant issues from the temperature even if they fired every round they carried in a burst because the round count would be so low.
      The heat dissipation is impacted, but the thermal mass of the weapon is still the same.

              It is getting negative reviews online, but I also saw somewhere that Company A has not made vocal support towards this week's crisis and the first two reviews are titled Company A is Bigot.

              I also have enough disposable income to afford this game while also retaining the ability to return or sell it should I have a physical copy.
              Now, I can play the game. If it's not good in 30 minutes, I'll play for another hour and make my final decision from there.
              Wow this a fun game, let me keep playing./This was bad, it is time to return it.

        Not transferring heat is exactly the problem. If your gun isn't radiating heat that means it's building up heat, and eventually it will reach the point of mechanical failure.

            First of all, yes they will. Second, long before melting, they will crack. Third, even if they don't, the rest of the gun probably won't be happy that your barrel is now up to welding temp. Fourth, I hope you enjoy being target painted by every hostile for thousands of miles because your gun is putting out as much IR as a ship's engine plume.

        Delay recoil impulse (to allow for the muzzle brake to do its work) but the spring shouldn't provide enough resistance to allow too much of the elongated remaining impulse to thrust too much. If you're shooting a gun in microgravity you're fighting bodily momentum and moment of inertia (rotation) with your thrusters which means you're burning delta-v. Minimizing that impulse as much as possible is the goal because you're either trying not to spin across space (shoulder firing/off CoG by countering with thrusters/RCS) or be pushed off (pulsing thrusters every often to zero out unwanted gains).

        Again this kind of conversation is wasted on a Starslop player.

          Alternate take on the spring: No spring but have a gas reservoir that taps off and holds some of the cycling gases to vent out through angled vents to return the action forward and act as the "spring" of the action. Reliability probably will take a shit for this type of action but the concept here is that the action is practically free moving linearly, relying on the muzzle brake to stop it from bottoming out. The gas reservoir acts to cycle it back and also to zero out momentum transfer. What recoil thrust occurs here is effectively sliding friction transfer of the action. Tolerances would be a bitch given the temperatures involved and thermal expansion (even low thermal expansion materials will have to deal with stupid cold + resist embrittlement and then go all the way up to hot for sustained use, thermal management or not given the delta)

          Again, pearls before swine of casuals.

          The order that forces are applied makes no difference to the resulting vector in a case like this. A heavier spring also doesn't delay the transfer of the energy from firing at all, it does the opposite (a less stiff spring transfers energy more slowly than an equivalent force stuffer spring). Your post just reveals you as a physicslet and mechanicslet.

            You misinterpret the concept of the spring being low strength enough just to cycle the action while the muzzle brake does most of the velocity reduction of the cycling mass but you do you with your projection.

              You're just describing a spring that doesn't bottom out. That's got zero to do with "making time for the muzzle brake to reduce velocity" because that's not a thing because the order that forces are applied doesn't change the resulting vector. Explain what "the order that forces are applied doesn't change the resulting vector" means, please.

                Lower spring strength means less force transfer and it'd be a long travel action with a progressive spring. The least compressed state would have the lowest force, if only to ensure action lockup on return and to minimize force transfer from when the propellant gases haven't interacted with the muzzle brake. The spring is there to function to bring the action back into battery more than anything. I don't expect propellant to be absolutely consistent burn to burn and thus the brake should be designed to counter less than 100% of the recoil impulse overall and the actual curve of the recoil impulse is designed to have as little up front and dump it as a long delayed flattened pulse towards the end.

                I think you can't visualize the long recoil action that's going on here where the spring is effectively holding the barrel-bolt assembly against the stop for the sake of accuracy. Ideally I'd want to not even have the spring force there and to cut it while instead relying on the return momentum to trip the lock up so initial travel is only fighting against recoiling mass. The brake slows down the coupled assembly just as it starts acting on the spring and acts as part of the unlocking action once the bolt is past the unlock position.

                No it doesn't. Everything else that follows from this in your post is wrong as a result or equally fundamentally retarded. Special mention for fundamentally retarded to your idea of a brake offsetting 100% of the recoil.

                I'll ask one last time and I'll try phrasing it differently and more explicitly for you.
                1. The final vector of a system to which you apply several forces does not depend on the order in which you apply those forces. *For systems with the attributes of this one under newtonian physics.
                2. It necessarily follows from 1 that the duration over which the forces are applied also does not influence the final vector, since duration is just the distribution of the same force over time (a continuous distribution of the "order").
                3. Thus, how can it matter how long a spring is? How can any spring remove energy from a system (reduce the scalar component) or redirect that energy (change the direction component)?
                4. Given 1-3, how can it matter what parts of the spring's cycle overlap with the operation of the brake or how offset they are or the order in which they are offset to the delta v cost of a shot, since we know that in all cases the final vector (the amount and direction we need to spend delta v to offset) will be identical?

    Ceaseless is bad, it’s maximum heat transfer to the host gun. A cased projectile is already dumping heat energy out of the gun. Liquid cooling and regular radiators are probably fine for normal infantry rifles, but for high ROF weapons, you’re going to want an ablative or spray coolant system. Some sort of thrust compensating system to prevent user rotation would probably be necessary for microgravity usage. Thermal sights would be great if you can make one that doesn’t white out when pointed in the general direction of the sun or an active rocket exhaust.

    Simple: don't. Infantry isn't going to deploy in the vacuum of space any more than they do in the sky or the sea. Infantry belong on the ground. The ground is something worth fighting for, so not a barren rock in the middle of literally nowhere, but a planet people can live on. Which assumes an earthlike atmosphere.
    For space combat, forget gay lasers and X-wings. Think a steel pipe with a nuclear machine gun. Now imagine that steel pipe bombarding any stupid bases set up on an unlivable planet. Why send infantry there? If some dudes are in a carefully managed space station in an utterly hostile atmosphere, just blow them up from orbit. Save the infantry fighting for shit you can't afford to blow up, like a livable planet where guns work just fine.

          Boarding also seems very unlikely just for the reason that either docking or entry via spacewalk requires a cooperative target. If they don't want you to board they'll just send the station into a rotation that's too fast for you to dock with. If you're boarding it's because the opposing target has surrendered and is at your mercy.

    .22's and grenades. in lower/zero gravity you dont need to worry about bullet drop or losing velocity, and simply puncturing a suit would be extremely bad, if not catastrophic. low recoil so easy to control your movement/rotation, and just dump drum mags of pointy bullets at many, many times the distance you could shoot on earth.
    same idea with the hand grenade. youd probably be able to throw a grenade on the moon about 2-3 miles unassisted. get yourself a potato cannon, or a slingshot, and now your lobbing grenades tens of miles away, with fragmentation that travels EXTREMELY far.
    not on the moon, but in the pure vacuum of space: crossbows, arrows tipped with explosives. no heat signature, no muzzle flash, no sound report, fire and forget. range: hundreds of miles. a compound bow can fire arrows at 200 mph. grenade shrapnel travels at roughly 16,404 feet per second, and would be dangerous hundreds of thousands of miles.

    while it would be extremely unlikely to get hit by shrapnel 500 miles away from a regular hand grenade exploding, the risk would not be 0.

        spacewalk suits already weigh about 280 pounds, and only gets you 8 and a half hours life support, which probably depletes a shitload faster if your doing something strenuous, like combat, i imagine there will be some technical difficulties in adding head to toe armor plating to every soldier, on top of the weaponry. an average us soldier carries 60-120 pounds of gear, and plate armor is about 30-50 pounds. so, 500-600 pounds per soldier. so assuming a one off, suicide mission thats expected to last less then say, 5 hours with no hope of return, you could probably cram about 150 of them onto a new glenn rocket. 20 million dollars per launch.

        but assuming that we just invent some magical weightless head to toe armor that doesnt make an incredibly bulky and unwieldy space suit even more fucking bulky and unwieldy, then spear guns. with nets on the end. catch them in a net, then attach your end, to a rocket. point at nearest sun, planet, or nothing, your choice.

      Starfield isn't anything like Skyrim if you look at the gameplay loop. There's no act of moving from point A to B, and seeing all this stuff in between as you traverse though the world map. In Starfield, every journey is a series of loading screens. There's little opportunity for distractions to arise.

      Lore doesn't center around a battle that makes little sense involving poor libertarians hopping into their advanced heavily armed spaceships. Constant complaints about xenomorphs/mechs instead of dropping bombs. Using the spaceships made me miss elite dangerous, but generally thought mechanics were inferior in Starfield. Shooter mechanics were standard and exploration/scanning got painful after a while.

      Skyrim was you burned down this village/you burned down that village. Haven't played it in a decade without heavy modding, but combat wasn't great. Exploration was just going to the next objective and something could happen on the way.

    A lot of guns in starfield are caseless, which makes sense if you're trying to save weight- but it makes no sense if we're considering the lack of radiators. In a vacuum, guns would overheat way faster.
    Would make sense if you combined it with some kind of replaceable heatsink,
